IPC: F16F1/12
Filed: 2002-09-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a coil spring for improving vibration absorption performance by preventing undulatory expansion and contraction caused by the resonance of coil winding.  <P>SOLUTION: The coil spring 1 is used as the damper member of an apparatus and a leaf spring-like auxiliary member 3 in a spiral shape is fixed along coil winding 2 via an elastic body 4 inside the coil winding 2. Since the resonance frequency of the coil winding 2 differs from that of the leaf spring-like auxiliary member 3, vibration is absorbed by the uniform contraction of the coil spring 1 by the elasticity of the leaf spring-like auxiliary member 3 even if external vibration that is equal to the resonance frequency in the coil winding 2 is propagated. Therefore, the coil spring 1 can maintain vibration absorption properties even to the external vibration at a frequency for resonating the coil winding 2.  <P>COPYRIGHT: (C)2004,JPO
